Patented Jan. 31, 1933 UNITED STATES PATENT orrlca ARTHUR IBROCKMAN, OF WOODRIDGE, NEW JERSEY, ASSEGNOR TO EBERHABD FABER PENCIL ('30., OF BROOKLYN, NEW YORK, A. CORPORATION OF NEW YORK CARTON Application filed January 20, 1932. Serial No. 58 7,6 19.

This invention relates in general to cartons, and more particularly to cartons of the type comprising two compartments each having an open end, and means hingedly connecting the cartons at their open ends so that sa d open ends may be closed by folding one compartment upon the other with one side of one compartment in juxtaposition to one side of the other compartment.

One object of the invention is to provide a carton of this character embodying novel and improved features of construction for holding the compartments together in closed positlon. Another object is to provide a carton of 1 this character in which the ends of the com partments opposite the open ends have closure flaps, and one compartment has a tongue formed integrally with one closure flap and projecting toward the other compartment 2 when the compartments are in juxtaposition,

while the other closure flap has a slit to frictionally receive said tongue, whereby the tongue and slit hold said compartments to gether and lock together said closure flaps to restrain them from pulling out of said compartments.

Other objects are to provide such a carton in which each of the closure flaps includes a main portion to close the end of the compartment and a flange at an angle to said main portion at the free edge thereof to tuck into said compartment, said tongue being struck up from said flange of one flap and hinged at the juncture of said flange with the main portion of the flap, while said slit is formed at the junction of said flange and main portion of the other flap to provide a carton such as described, wherein the side of the compartment adjacent said slit extends beyond the junction of the main portion and the flange of the corresponding closure flap when said flap is closed, whereby said tongue frictionally engages the edge of said side of the compartment to restain the tongue from pulling .out of said slit; to provide a tongue and slit construction of the character described, wherein the shank of the tongue is of a width approximately equal to the length of the slit and the extremity of the tongue is wider than the slit so as to be insertible therethrough by force, whereby said extremity holds the tongue in said slit; and to obtain other advantages and results as will be brought out by the following description.

Referring to the accompanying drawing, in which corresponding and like parts are designated throughout the several views by the same reference characters,

Figure 1 is a perspective view of a carton embodying my invention;

Figure 2 is a transverse vertical sectional view through the carton;

Figure 3 is a vertical longitudinal sectional View, on the line 3-3 of Figure 2;

Figure 4 is a fragmentary bottom plan view of the carton, with portions broken away and shown in section; v

Figure 5 is a fragmentary perspective view of one end of one of the compartments, showing the closure flap having the slit, and

Figure 6 is a similar view, showing the closure flap having the tongue.

Specifically describing the illustrated embodiment of the invention,-the carton includes two compartments 1 and 2 made of cardboard or other suitable material, each of which has an open end 3. The compartments are hingedly connected at their open ends by an integral portion 4 which permits the compartments to be folded one upon the other, with one sideof one compartment in juxtaposition to one side of the other and with the portion 4; closing the open ends, as shown in Figures 1 and 2.

The other ends of the compartments 1 and 2 have the respective closure flaps 5 and 6. The flap 6 has a main portion '7 hingedly 7 connected at one edge to one side of the compartment 2, as indicated at 8, to close the end of the compartment, and a flange 9 project- 11 of the closure flap 5 and is hinged at the juncture of the main portion 10 and the flange 11, so as to project toward theother compartment when the compartments are arranged-in juxtaposition, as shown in Figures 1 and 2. A slit 13 is formed in the flap 6 at the juncture of the main portion 7 and the flange 9, to frictionally receive the tongue 12 when the compartments are in j uxtaposition.

The tongue and slit 12 and 13 serve to hold the two compartments in juxtaposed relation and to lock the two closure flaps 5 and 6 together, so as to restrain them from pulling out of the respective compartments. The tongue 12 normally projects from its corresponding compartment, as shown in Figure 6, and as the two compartments are brought into juxtaposed relation, the tongue is inserted into the slit 13, as clearly shown in Figures 2 and 4:. Preferably, the shank 1 1 of the tongue is of a width approximately equal to the length of the slit 13, while the extremity 15 of the tongue is somewhat greater in width than the length of the slit, so that this extremity is insertible through the slit by force, and after the tongue has been inserted into the slit, the extremity 15 restrains the tongue from pulling out of the slit. Also, preferably, the side of the compartment adjacent the slit 13 is extended, as

taposition to each other and inserting the tongue 12 into the slit 13, it being understood that the closure flaps must be tucked into the compartments for this purpose. The closure flaps 5 and 6 may also be opened, if desired, to permit access to the compartments. This is an especially advantageous combination, in that the closure flaps have a tendency toward relative 'movement, which increases the frictional engagement of the tongue with the sides of the slit to prevent the tongue from pulling out of the slit, and the tongue and slit serve to restrain the flaps from pulling out of the respective compartments.

It will be understood by those skilled in the art that the details of construction of the carton may be modified and changed without departing from the spirit or scope of the invention, and therefore I do not desire to be understood as limiting myself in the construction and use of the invention, except as required by the following claims when construed in the light of the prior art.

Having thus described the invention, what I claim is:

1. A carton comprising two compartments each having an open end and a closure'fl'ap at the other end, said compartments being hingedly connected at their open ends so that said open ends may be closed by folding one compartment upon the other with one side of one compartment in juxtaposition to one side'of the other, said closure flaps being hinged to said compartments with their free edges disposed at the juxtaposed sides of said compartments, each of said closure flaps having a main portion to close the end of the corresponding compartment and a flange at an angle to said main portion on the free ed e thereof to tuck into said compartment, t e closure flap of one compartment having a tongue struck up from said flange of said flap and hinged at the juncture of said'flange and the main portion of the flap and project ing toward the othercompartment when said compartments are in juxtaposition, the clo sure flap of the other compartment havinga slit at the juncture of the main portion-and the flange of said flap to frictionally'receive said tongue, whereby said tongue and slit hold said compartments together and lock said closure flaps together to restrain them from pulling out of said compartments.

2. A carton-comprising two compartments each having an open end and a closure flap at the other end, said compartments being hingedly connected at their open ends so that said open ends may be closed-by folding one compartment upon the other with one side of one compartment in juxtaposition to one side of the other, said closure flaps being hlnged to said compartments with their free edges disposed at the juxtaposed sides-of said compartments, and each of said closure flaps having a main portion to close the endof the compartment and a flange at an angle to said main portion on'the free edge thereof to tuck into said compartment, said closure flap of one compartment having a tongue struck up from said flange in hinged relation theretoat the junction of said flange with'said main portlon of the flap and projecting toward the other compartment when said compart- 'ments are in juxtaposition, while the closure flap of the other compartment has a slit'at the junction of the flange and the main portion of said flap to frictionally receive said tongue, the side of said compartment adjacent said slit extending beyond the junction of the main portion and the flange of the corresponding closure flap, whereby said tongue when inserted into said slit frlctionally engages the edge of said side of the compartment to restrain the tongue from pulling out of said slit and said tongue and slit hold said compartments together and lock together said closure flaps to restrain them from pulling out of said compartments.
